Introduction: Postbox From an Ammunition Container

Picture of Postbox From an Ammunition Container

I am currently away at sea, so my opportunities to make stuff are limited.

However we're not going to let a little thing like no access to shops etc stop us are we?

So using stuff I found onboard I have constructed a post box, fortunately I have a fully equipped machine shop on the Sleek Grey Car Ferry of Death, so that helps

Step 1: Materials, Tools Etc

Picture of Materials, Tools Etc

An Ammunition Box (we have lots of these hanging around but they can be bought from Army Surplus Stores)

Grinder with cutting wheel

Drill and bits


2 x M12 bolts 50mm long

3 x M12 nuts

2 x Large washers

Small padlock

Step 2: Construction

First I got my ammunition box and using a grinder and cutting wheel cut a slot as shown.

The original idea was to cut this shape and bend up the "flap" as a letterbox hole, but quite frankly it looked a bit crap so...............................

I cut out a complete triangle instead

Step 3: Securing the Lid

I drilled a hole both short sides through the centre slot of the closing handles

On the side I want to open I fitted an M12 bolt which I had filed flats on the thread and drilled a hole for the padlock

On the non opening side I bolted an M12 straight through to secure the lid, the pivot action of the closing handle allows this to move to open the box, I used a washer inside the box and one under the handle to spread load

Step 4: Finishing

It just needs a bit of paint (if I can liberate some from one of the armoured vehicles down stairs!) a mounting pole from the diy shop and a padlock and it's done!

And when I get home I can install it (probably much to my wife's disgust!!!!!)

I like it! Postal Service may not, so might put a postal decal on it somewhere.

The postal Service in NZ don't give two hoots what your postbox is like ( we have everything from Milk churns to model houses) as long as there is a box of sorts and they can reach it from the van window
